How to rewind an electric motor anchor at home

[shapanwwuom]

If you have the skills to repair equipment and a minimum set of tools, then rewinding the anchor at home will help to eliminate the malfunction.The thing is that it is the winding that takes the first "blows" of improper operation. The conductor wires break and burn. Replacing them will extend the life of the equipment and increase the engine's performance.

Before starting repairs, prepare tools and materials:

multimeter. If you don’t have one, you will need a voltage indicator, a megohmmeter, and a 12 V light bulb with a power of 30–40 W;
new winding. The diameter of the core must be identical to the diameter of the old winding;
soldering iron;
dielectric cardboard 0.3 mm thick;
varnish or epoxy resin;
a skein of thick cotton thread;
sandpaper.
In order not to do unnecessary work, it is important to correctly india telegram data identify the cause of the equipment failure. To do this, inspect the tool and check whether the current is supplied to the collector and the start button using a multimeter or indicator. If everything is in order, then you need to inspect the device from the inside.

Engine diagnostics
Disconnect the tool from the power supply and disassemble the body. Smell the rotor. If an interturn short circuit has occurred, the insulating coating melts and emits a sharp smell.

When there are no external signs of a malfunction, it is worth checking the anchor lamellas with a multimeter. Switch the device to the ohmmeter mode and set the range to 200 Ohms. Use two probes to "ring" the adjacent lamellas. A change in resistance indicates a breakdown in the coil.

The ohmmeter can be replaced with a light bulb. Connect the plus and minus terminals to the device plug, and put the bulb in the gap. Rotate the armature shaft by hand. If the bulb "blinks", then there is an interturn short circuit. The bulb is not lit? This means there is a break in the circuit or there is no resistance in one of the lamellas.
